Product Description

Product Description

Design of the Fuse Holder

1. A flapper valve is available inside the upper portion of the outer tube.
This flapper valve closes when the inner fuse cartridge assembly is removed. This results in minimal oil leakage from the transformer tank during fuse link replacements
reduces potential risk of environmental damage
reduces potential oil contamination to the rubber cable accessories
reduces potential spillage during installation and/or replacement of the transformer,

2. Copper contacts for connection to the transformer.
NJREC Bayonet Fuse Holders are designed to be used with Current Sensing, Dual Sensing, and Dual Element fuse links. The Bayonet Fuse assembly must be used in series with a current limiting fuse, or isolation link to prevent the possibility of a high current fault. Partial range current limiting fuses use the low current clearing capabilities of the Bayonet Fuse assembly while protecting the transformer or apparatus from high current internal faults that could cause failure to the specific piece of equipment, as well as other system damage.
